Thanks for replying, I've got .NET 3.5, and 4 client on the server, and C++ redistributables 2008??
I downloaded an already compiled core to try that, and the same result..
Do you think I should try C++2010 and those redists?
when I compare what the XP box has that the server doesn't, the only thing that stands out is that the XP box has .NET1.1 on it (and all the other .NET's up to 4 client).. but surely it can't be that?
